The Pt-Co (Platinum Cobalt) 500CU APHA/Hazen Color Standard is a certified reference material designed for accurate colorimetric analysis in water and wastewater testing. This standard solution is prepared using precise starting materials—Potassium chloroplatinate and Cobalt chloride hexahydrate—as specified by the ASTM D1209-05 method and Standard Method 2120C. It is suitable for use with UV/Vis spectroscopy to determine impurities in near-colorless samples.
